Sprint's push-to-talk app adds support for six new phones

Sprint is bringing push-to-talk functionality to six new devices today: the Samsung Galaxy S4, Galaxy Note 3, LG G2, LG G Flex, LG Optimus F3, and the Kyocera Hydro Edge. The feature comes by way of Sprint's Direct Connect Now Android app, and allows user to chirp at friends who are using Sprint's Direct Connect services (and annoy everyone around in the process), as long as both have their feet firmly planted on US soil. In addition to today's announcement, support for the Galaxy S4 Mini, Galaxy Mega, and Sprint Spark edition Galaxy S4 are expected to arrive soon.
